TENSION-REGULATOR FOR SPlNDLE-DRIVING BANDS.

SIECIFICATION forming part of Letters Patent No. 395,240, dated December 25, 1888.

Application filed August 25, 1888.

To all whom it may concern.-

Be it known that I, PATRICK L. KENNEY, a citizen of the United States, residing at Pittsfield, in the county of Berkshire and State of Massachusetts, have invented a new and useful Improvement in Tension-Regulators for Spindle-Driving Bands, of which the follow in g is a specification.

, The object of this invention is to provide an improved tension-regulator for spindledriving bands; and it consists in a certain novel construction and combination of devices fully set forth hereinafter in connection with the accompanying drawings, and specifically pointed out in the appended claims.

In the drawings, Figure 1 is a plan view of a portion of the carriage of a spinning-machine, showing the improved tension-regulator applied in the operative position thereto. Fig. 2 is a detail sectional view to show the manner of securing the idler-pulleys to the swinging arm. Fig. 3 is a detail view.

Referring by letter to the drawings, A designates the portion of the carriage in which is mounted the usual driving cylinder or drum C, and (l 0' represent the spindles, which are provided with the pulleys or whirls D I). The endless band E passes around the driving cylinder or drum and also around each pulley or whirl 1), whereby, as the cylinder or drum is rotated (by mecl'lanism not shown in the drawings) the spindles will be rotated.

Intermediate points of the driving-band are passed around the idler-pulle i E, which are attached at suitable points to the swinging arm G, which is pivoted at one end to the frame of the carriage on the removable vertical pin g. This pin engages in one of a series of sockets, g, which are formed in the frame of the carriage. The said pulleys are mounted on spindles ff, which are attached at their inner ends to the collars II II, embracin the swinging arm. These collars, as will be obvious, are capable of rotary adjustment on the swinging arm, thereby allowing the pulleys to be arranged at any desired angle thereto to enable them to be aligned with the portion of the driving-band which extends from the said idle-pulleys to the ad j acent spindles, and the collars are provided with set-screws I I, whereby they may be clamped in the preferred position. These Serial No. 283,699- (No model.)

idle-pulleys are also capable of longitudinal adjustment on the swinging arm to enable them to be separated to take up any permanent slack of the driving-band irrespective of the automatic adjustment afforded by the swinging arm. The swinging arm is further provided. at a suitable point near its free end with the adjustable collar K, provided with a set-screw, L1, and to this collar is attached one end of a contractile spring, L, the opposite end being attachedto a convenient partof the carriage. This spring draws the free end of the swinging arm away from the pulley or whirls which are attached to the spindles, and consequently holds the driving-band taut or at a suitable tension to insure the accurate operation of the various parts of the machine.

Instead of the spring a weight may be connected by a suitable cord to the free end of the swinging arm, the said cord passing over a pulley, L, in nearly the same horizontal plane of the arm, whereby the latter is drawn in the proper direction, as shown clearly in Fig. 2 of the drawings.

\Vith this tension device there is no straining of the band by being drawn too tight at times, for the reason that the swii'iging arm is automatically adjustable and maintains a constant tension, and therefore the speed of rotation of the spindles remains the same and the tension or strain on the yarn remains con stant.

M represents a guide-bar, which is arranged across the carriage below the swinging arm, and it is provided with a series of apertures or sockets, m m, in which are adapted to be engaged pins N N, respectively on opposite sides of the swinging arm, whereby if the band or the spring should break in the operation of the machine the parts would retain the same relative positions, an d therefore would require but little adjustment when the broken part is replaced; also, the said adjust-able pins may be employed to hold the swinging arm in the desired position irrespective of the spring or weight, and therefore permit the continuance of the operation of the machine even after the spring is broken. n

The driving-band is arranged on the spin dles and cylinder as follows: It is carried from the cylinder to and around the spindle at one end of the carriage, thence to and around the adjacent idle-pulley on the free end of the swinging arm, thence to and around the idlepulley at the opposite end of the carriage, near the pivoted end of the swinging arm, thence around the adjacent spindle, and then from the cylinder to the spindles and back until the otherend of the carriage is again reached.

Any number of spindles may be employed, and the band may be guided in various ways; but I prefer the above as being the most effective.

Having thus described my invention, I Glaim 1. The cylinder or drum, the spindles provided with suitable pulleys or whirls, and the endless band passing around the cylinder or drum and the pulleys or whirls, in combination with the swinging arm, the longitudinally-adjustable idle-pulleys arranged thereon and having the band passing therearound, the said pulleys being adapted to be separated or arranged closer together to take up or allow fora permanent slacking or contraction of the band, and the spring or equivalent tension device connected to the free end of the arm, substantially as specified.

2. The combination, with the cylinder or drum, the spindles provided with suitable pulleys or whirls, and the endless band passing around the cylinder or drum and the pulleys or whirls, of the swinging arm G, pivoted at one end to the carriage of the ma chine and provided with the adjustable collars H H, having spindles ff, the idle-pulleys F F, mounted on the said spindles and adapted to be arranged at an y desired angle, and the spring or its equivalent connected to the free end of the said swinging arm, substantially as specified.

The combination, with the cylinder or drum, the spindles provided with suitable pulleys or whirls, and the endless band passing around the same, of the swinging arm provided with the idler-pulleys F F, having the endless band passing therearound, the sprin or its equivalent connected to the free end of the swinging arm, the guide-arm arranged adjacent to the swinging arm and pro vided with a series of apertures or sockets, and the pins engaging the said apertures or sockets on opposite sides of the swingin arm, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto at'fixed my signature in presence of two witnesses.

PATRICK L. KENNEY.
